Redness around the nostrils of a Blue & Gold Macaw
My blue and gold macaw, who I recently adopted from an owner who could no longer care for him, has some redness around his nostrils and abit on his cheeks, almost like he is flushed. He has a tendency to rub his beak on things such as his perches, but I think he may be using the rubbing motion because his nose is itchy.
I'm worried he could be ill, or be having some sort of a reaction to something in his environment. Do birds have allergies to things such as cats, horses, pollen, dust etc like people? Is there anything I can do to figure out an allergy and to treat an allergy?
